这个七月像是魔障了,飞机接二连三地出事。我所采访的这家小企业——禾讯科技,曾运用卫星数据寻找马航MH370,马航M17宣布坠毁的第一时间我又联系到这家公司的CEO向涛。他坦言,这次卫星没啥优势。位置确定,确认坠毁,地面的照相机都拍得比卫星清楚。“卫星最大的问题是,卫星在绕地球运动,不是任何时候任何地方上空都有遥感卫星,如果那个时候恰好有事发生,卫星(不在那个位置)无法捕捉到当时的情景。”目前精度较高的商业卫星能达到0.5米,也就是0.5乘以0.5的正方体,在卫星上就是一个单点。简单来说,卫星顶多能做到分辨出地上的车型,是辆卡车还是辆轿车。采访禾讯就像上一堂卫星科普课,它的客户也五花八门,比如一直苦恼于拆迁还建问题的房地产商,希望能依靠卫星提供证明,证明某些房屋 This July is like a magic barrier, the aircraft accident after another. I interviewed this small business - Wo Information Technology, had used satellite data to find the Malaysia Airlines MH370, Malaysia Airlines M17 announced the first time I crashed the company I contacted the Tao. He admitted that this satellite has no advantage. Confirm the location, crashed, cameras on the ground were more clearly photographed than the satellite. “The biggest problem with satellites is that satellites orbiting the Earth do not have remote sensing satellites anywhere at any time, and if that happens to happen then the satellites (not in that position) will not be able to capture the situation at the moment.” " High commercial satellite can reach 0.5 meters, which is 0.5 by 0.5 cube, on the satellite is a single point. In simple terms, the satellite can at most distinguish between the models on the ground, whether it is a truck or a sedan. Interview with Wo is like a satellite science class, its customers are varied, such as real estate developers have been distressed in the demolition of the issue of construction, hoping to rely on the satellite to prove that some of the housing
